[PATCH] ARM: include linux/bug.h in insn.c

[Joachim Eastwood]

After commit d82227cf8 building the kernel fails with:
  arch/arm/kernel/insn.c: In function '__arm_gen_branch_thumb2':
  arch/arm/kernel/insn.c:13: error: implicit declaration of function 'WARN_ON_ONCE'
  make[1]: *** [arch/arm/kernel/insn.o] Error 1
  make: *** [arch/arm/kernel] Error 2

insn.c uses WARN_ON_ONCE so lets include bug.h.
